The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Embodiment one
As shown in Figure 3, according to the structural representation of the shock attenuation unit of the utility model embodiment, it comprises: shock absorber 2, yoke 4, upper bracket 5, lower bracket 6, upper pin 3 and lower bearing pin 7.
Wherein shock absorber 2 comprises the cylinder barrel 21 on top and the plunger 22 of bottom, and its two ends have trepanning.
As shown in Figure 4 again, the top of upper bracket 5 is columnar structured 51, and the bottom is a fixed part, and fixed part is through being spirally connected or welding manner is fixed on the outside of belly 10; Preferred construction is: offer at least two screws 52 on the fixed part, it is fixed on through screw or rivet on the outside of belly 10 of vehicle frame 1, and the hole 53 of upper bracket 5 top cylinder shape structures 51 is parallel with the top airfoil 9 of vehicle frame 1.
As shown in Figure 5 again, an end of yoke 4 is an axle journal 41, and the other end is a fork portion 42.Wherein axle journal 41 is a column, and it comprises two sections columns that diameter is different in the present embodiment, and is bigger away from the column diameter of fork portion 42 1 ends near the column diameter of fork portion 42 1 ends; Have screw thread on the column away from fork portion 42 1 ends, can pass through nut screwing clamping.Have a hole on the column away from fork portion 42 1 ends, be used to insert screw and connect; Also be provided with porose in the fork portion 42.Axle journal 41 stretches in columnar structured 51 the hole 53 of upper bracket 5 into, stretches out columnar structured 51 part and fixes with nut, has the gap between axle journal 41 and the hole 53, makes axle journal 41 in hole 53, can rotate; Fork portion 42 is through the trepanning free-running fit of upper pin 3 with shock absorber 2 upper ends, and shock absorber 2 can rotate around upper pin 3.
As shown in Figure 6 again, an end of lower bracket 6 has hole 61, and the other end has parallel two holes 62 and 63, and hole 61 is vertical with the direction in hole 62,63.Captive joint with lower bearing pin 7 in hole 61, lower bracket 6 is fixed on the leaf spring 8 through hole 62 and 63, and the trepanning and the lower bearing pin 7 of shock absorber 2 lower ends are hinged, are provided with buffer rubber gasket between the two, to play buffer action.In the car load actual travel, this relative motion amount between the two is very little.
The principle of the shock attenuation unit of the utility model is following:
In the car load driving process, lower bearing pin 7 is with leaf spring about in the of 8, all around motion.Shock absorber 2 structures own are equivalent to a hydraulic actuating cylinder, and its plunger 22 slides in cylinder barrel 21 when the vehicle up-and-down movement, thereby can coordinate leaf spring 8 up-and-down movements; The difference of shock absorber 2 and hydraulic actuating cylinder is that the fluid of plunger both sides in the hydraulic actuating cylinder flows into through oil pipe or the outflow cylinder barrel; Belong to outer circulation; And the fluid of plunger 22 both sides in the shock absorber 2 is from an effluent to opposite side through the fuel tap on the plunger 22; Circulation in belonging to, fuel tap can be controlled the pressure of fluid, thereby obtains shock absorber 2 needed dumping forces.When leaf spring 8 seesawed, shock absorber 2 rotated around upper pin 3, also does slight rotation around lower bearing pin 7 simultaneously.When the leaf spring side-to-side movement, the power that the upper end of shock absorber 2 acts on upper pin 3 can make the axle journal 41 of yoke 4 in the hole 53 of upper bracket 5, rotate.When seesawing when the side-to-side movement combined action of leaf spring 8, shock absorber 2 rotates around upper pin 3, and the axle journal 41 of yoke 4 rotates in the hole 53 of upper bracket 5 simultaneously.
Embodiment two
The utility model also provides a kind of automobile, comprises the shock attenuation unit in the foregoing description.
Can find out by above embodiment; The utility model embodiment connects upper bracket and shock absorber through adopting yoke; Make the shock absorber coupling end rotate up and down all around, thereby adapt to the motion of leaf spring, solved the eccentric wear problem of shock absorber in the prior art effectively with respect to suspension.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection domain of the utility model.
